GLUE-SPREADING MACHINE.

Application filed May 4-, 1917,

T all whom it may concern Be it known that I, ARTHUR H. Donor-r- ERTY, a citizen of the United States, residing at Russellville, in the county of llamblen and State of Tennessee, have invented a new and useful Glue-Spreading Machine, of which the following is a specification.

The present invention relates to a machine for applying glue or other liquid to the edges of stock, such as used in the construction of table tops and the like, and it is the objectof the invention to provide a novel and improved apparatus of that nature which provides for economy, in that time, labor and material are saved, the machine eliminating the surplus application or waste of glue, since only a thin even film of glue is applied to the stock.

Another object of the invention is to provide a glue spreading machine which is designed to apply the glue to boards or other objects of various widths and thicknesses, and to both edges thereof, which is superior to the gluing of one edge of each board only, which results in the glue being chilled or jellied.

It is also the object of the invention to provide a machine of the nature indicated which is comparatively simple and inexpensive in construction and which performs its otfice in a thoroughly practical and efii cient manner.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein V Figure 1 is a plan View of the machine.

Fig. 2 is a vertical section on the line 2-2 of Fig. 1. i

The machine embodies a suitable frame 1 carrying a double walled glue tank or trough 2 in which the glue is heated, such as applying steam between the walls of the tank by means of pipes 3.

A shaft 4 is journaled in bearings 5 at the ends of the tank and said shaft extends longitudinally over said tank, being pro- Specification of Letters Patent.

Patented Apr. 2, 1918.

Serial No. 166,394.

feathered upon the shaft 4 to slide toward and away from One another, and the adjacent sides of the disks are provided with flared flanges 9 which prevent the glue from running down the faces of the disks to the shaft l, since any glue which flows toward the center of the disks will be caught by the flanges 9 and will drip therefrom back into the tank.

A pair of arms 10 is pivoted, as at 11, upon the frame at one side of the tank 2 and project to aid the tank and have their free ends overhanging the same and carrying glue applying wheels 12 rotatable in horizontal plane while the disks 7 rotate in vertical planes. The remote portions of the wheels 12 contact with the faces of the disks 7, and said wheels 12 have soft rubber tires 13 to carry the glue.

A coiled wire retractile spring 14 is connected to the frcc ends of the arms 10 for swinging them toward one another to move the wheels 12 likewise, and coiled wire rctractilc springs 15 connect the disks 7 for moving them toward one another and holding them in contact under spring tension with the tires 13.

In order to separate the arms 10 for separating the wheels 12 and disks 7 therewith.

flexible elements 16 are connected to the arms and pass through suitable guides 17 carried by the frame, and are attached to a treadle 18 carried by the frame, which when depressed will pull the elements 16 to swing the arms 10 away from one another. This will separate the wheels 12, which will push the disks 7 away from one another with them. It is thus a convenient matter to separate the wheels 12 for various widths of boards by depressing the treadle properly.

The frame 1 carries a table 19 on which the stock is seated and slid between the wheels 12. The disks 7 in being rotated will elevate the glue therewith, and the tires 13 in bearing against the faces of the disks 7 will carry a film of glue with them and apply the glue to both edges of the stock which passes between the wheels 12, said wheels being rotated by their engagement with the disks 7 to thereby carry the stock through the machine when fed between the wheels 12. In this manner, a uniform thin film of glue is applied to the stock, to avoid the waste of glue. The machine also saves time and labor, which in addition to the saving in glue, renders the machine preferable to methods of applying glue now used. The tires 13 being of soft rubber, can yield to conform to the tongue and groove edges of the stock for effectively applying the glue thereto. 7

In order to wipe surplus glue from, the edges of the stock, brackets 20 are carried by the free ends of the arms 10 and have brushes 21 between which the stock passes as it leaves the wheels 12. Enaid brushes will brush ofi the surplus glue, which will run back into the tank. By thus providing a thin, even film of glue on both edges of each board, the boards can be united more efii ciently than with prevailing methods.

Having thus described the invention, what is claimed as new is 1. A liquid spreading machine embodying a tank, an elevating disk rotatable about a horizontal axis to dip in the contents of the tank and mounted for movement along said axis, and an applying wheel at an angle with said disk having its periphery contacting with one face thereof, said applying wheel being movable to accommodate the stock and the disk being movable therewith.

2. A liquid spreading machine embodying a tank, a disk mounted for rotation and sliding movement on a horizontal axis to dip in the contents of the tank, an applying wheel mounted at an angle with the disk for rotation and shifting movement to accommodate the stock, and spring means for holding said disk and wheel together with the periphery of the wheel and one face of the disk in contact.

3. A liquid spreading machine embodying a tank, a movable member, an applying wheel carried for rotation by said member to accommodate the stock, an elevating disk to dip in the contents of the tank and having one face contacting with the periphery of said wheel, means for mounting said disk for rotation about and movement along a horizontal axis, and spring means for holding said disk against said wheel.

4:. A liquid spreading machine embodying a tank, a pair of elevating disks to dip in the contents of the tank and mounted for rotation about and relative movement along a horizontal axis, a pair of applying wheels disposed between said disks at an angle therewith for the movement of the stock between said wheels in contact therewith, and spring means for moving saidv disks toward one another to bring their adjacent (Copies of this patent may be obtained for faces into contact with the peripheries of said wheels.

5. A liquid spreading machine embodying a tank, relatively movable members, applying wheels carried by said members to move toward and away from one another to accommodate the stock therebetween, elevating disks to dip in the contents of the tank and mounted for rotation about and relative movement along a horizontal aXis, said wheels being disposed between the disks to contact with the faces of said disks, and spring means for moving the disks toward one another into contact with the peripheries of said wheels.

6. A liquid spreading machine embodying a tank, a horizontal shaft extending over said tank, disks, carried by said shaft for rotation and relative movement thereon toward and away from one another, a pair of movable members, wheels carried for rotation by said members at an angle with said disks and disposed between said disks to contact with the adjacent faces thereof, said wheels being movable with said members toward and away from one another to accommodate the stock therebetween, and a spring means for moving said disks toward one another to contact with the peripheries of said wheels.

7. A glue spreading machine embodying a tank, an elevating disk to dip in the contents of the tank and mounted for rotation about and movement along a horizontal axis, a movable member, an applying wheel carried by said member for movement therewith, said wheel being at an angle with the disk to have its periphery contact with one face of the disk, spring means for holding said disk and wheel in contact, and a brush carried by said member in contact with the stock after passing said wheel.

8. A glue spreading machine embodying a tank, a shaft extending across the tank, glue elevating disks slidable upon the shaft, a pair of pivoted arms, glue applying wheels carried by the arms between said disks, spring means for moving the disks toward one another against the remote portions of said wheels, means for separating said arms, and brushes carried by the arms for the movement of the stock therebetween after passing between the Wheels.

In testimony that I claim the foregoing as my own, I have hereto affixed my'signature' in the presence of two witnesses.
